Push Lawn Mower Won’t Start With Fresh Gas

So you just put some fresh gas in your lawn mower and it refuses to start when you pull the cord. You pull and pull and pull and it still won’t start or it may sputter a little. But how can that be when you just put fresh gas in your lawn mower?

Well, it could be that your lawn mower sat all winter long and the gas that is in it has gone bad. The gasoline with ethanol in it today only lasts about 90 days before it starts to go bad. Once it goes bad in the carburetor, it begins to plug up the idle and main jets and then the lawn mower is not going to run at all or barely run.

A mixture of fresh and bad gas doesn’t solve the problem either. It will still cause the same non starting problem and you will be pulling until your arm wears out and have the same results. The carburetor must be removed and cleaned and all gas emptied from the system and fresh gas added before you attempt to start the lawn mower once again.

My Lawn Mower Dies and Will Not Restart

This is a fairly common problem and it seems to get worse when it gets hot outside. After a while the lawn mower will restart and then you can mow for a while and then the same thing happens over again.

The most likely culprit here is that the ignition system is heating up and then breaking down inside. When it breaks down, it will cause the ignition coil to stop producing spark and thus the engine dies.

When your engine does die, test for spark by installing an inline spark tester and then cranking the engine. If you do not see any spark, you can assume that your ignition system is at fault. Further testing will need to be performed to narrow down the issue. You will need to know if it is the engine or the machine kill system. You can isolate this by disconnecting the kill system and then checking for spark.
